TECHNICAL FIELD

This invention relates to a novel triazole compound and a pesticide.

BACKGROUND ART

A host of insecticides and acaricides have been heretofore used. It is not a few of them that hardly deserve to be called completely satisfactory pesticides because they are deficient in effect, because they find only limited use owing to the problem of growing tolerance on the part of pests to be controlled, because they do harm to or contaminate economic plants to be protected, or because they manifest unduly high toxicity to men, beasts, and fish inhibiting the districts in which they are used. Thus, the desirability of developing a chemical reagent that suffers only sparingly from such drawbacks as mentioned above and ensures safe use has been finding enthusiastic recognition.

As a substance which is associated with this invention, the compound of the following formula is disclosed in Bull, Chem. Soc. Jpn., 56, 545 (1983). ##STR2##

And the compound of the following formula is also disclosed in Journal of Pharmacy, 94 (1), 55 (1974). ##STR3##

The relevant monograph of this publication, however, has no mention of the compound possesing an insecticidal or acaricidal effect.

In recent years, numerous species of harmful insects such as diamondback moth, planthopper, and leafhopper have come to build tolerance to organophosphate reagents, carbamate reagents, and acaricides. The inability of these reagents to manifest necessary effects has been posing a serious problem. A need has arisen for chemical reagents which are capable of effectively destroying harmful insects and mites of the species which have built tolerance. The compounds according to this invention are chemical reagents which manifest satisfactory insecticidal and acaricidal effects not only to insects and mites of the aesthetic species but also to the insects of the species tolerating carbamate reagents and pyrothroid reagents and the mites of the species tolerating acaricides.

Further, the compounds according to this invention produce only sparlngly low toxicity, do only insignificant harm to fish and hybrid animals, and enjoy pronnounced safety.

The compounds according to this invention ran also be used as antifueling agents for preventing aquatic organisms from attaching to ship bottoms and fish nets.

Insocticidal and acaricidal agents!

The compounds according to this invention which are produced as described above can be used for actual application in their pure form, namely without addition of other components. For application in agriculture, they may be prepared in various forms allowed for standard agricultural chemicals such as, for example, wettable powders, granules, dusts, emulsifiable concentrates, solutions, suspensions, and flowable powders.

As additives and carriers for solid preparations, plant powders such as soybean grains and flour, finely powdered mineral materials such as diatomaceous earth, lime, gypsum, talc, bentonite, pyrophyllite, and clay, and organic and inorganic compounds such as sodium benzoate, urea, and Glauber's salt. For liquid preparations, oil fractions such as kerosine, xylene, and solvent naphtha, cyclohexane, cyclohexa-none, dimethyl formamide, dimethyl sulfoxide, alcohols, acetone, trichloroethylene, methylisobutyl ketone, mineral oils. vegetable oil, and water are used as solvents. These preparations allow addition thereto of a surfactant when necessary for the purpose of assuming a homogeneous and stable form. Properly, these preparations contain the compound as an active component at a concentration in the range of 5 to 70%. The wettable powder, emulsion, and flowable agent are diluted with water to prescribed concentrations and are used in the form of a suspension or emulsion and the dust and granules are sprayed in their unmodified forms.

Test Example 2 (Effect against two-spotted spider mite)

The kidney beans sown in pots 2 suns (equivalent to about 2.3 inches) in diameter were grown. To the primary leaves of the plants grown for seven to ten days after germination, 17 adult females imagoes of two-spotted spider mites, which is resistant strain to organo phosphate reagents were inoculated and were sprayed with a chemical solution prepared by diluting the wettable powder of the formulation of Example 7 with water to a compound concentration of 125 ppm. The kidney beans were left growing in a constant temperature room kept at a temperature of 25° C. and a humidity of 65%. Three days after the spray, the adults were removed from the plants. On the 11th day in the room, the plants were examined to determine whether or not the eggs oviposited by the adults during the three days mentioned had developed to the stage of adult and rate tho ratio of extirpation. The results are shown in Table 3. The ratio of extirpation was determined in accordance with the following formula.

    Ratio of extirpation (%)= (Number of adults in the non-treated plot)-(Number of adults in the treated plot)!÷Number of adults in the non-treated plot)×100
